I'm trying to understand how similarities in trademarks are dealt with. To take an example (that I used in a previous unrelated question), assuming a trademark existed for "BodyLife", a company trying to help people improve their health through exercise, would a similar company be able to register and use a trademark like "BodyForLife"?
I'm interested in how a one word difference plays.
How are those conflicts resolved? Is it the trademark bureau to accept or not accept (and can this decision be appealed), or is it done mostly through litigation?
